f2fe752d6b More inithosts() fixes:
o Don't free(3) memory occupied by host structures
  already in the host list.
o Set hrp->hostinfo to NULL if a host record has to stay in
  the host list, but is to be ignored.  Selecthost() knows that.
o Reduce the pollution with excessive NULL checks.
o Close a couple of memory leaks.

o getaddrinfo(3) returns int, not pointer
o don't leak memory allocated for hostnames and hostinfo structures
o initialize pointers that will be checked for NULL somewhere

a117c34534 Rework storing files thoroughly. This includes:
o Remove the race between stat(2) & fopen(3) when creating
  a unique file.

o Improve bound checking when generating a unique name from
  a given pathname.

o Ignore REST marker on APPE.  No RFC specifies this case,
  but the idea of resuming APPE's implies this.

o By default, deny upload resumes and appends by anonymous users.
  Previously these commands were translated to STOU silently,
  which led to broken files on server without any notification
  to the user.

o Add an option, -m, to allow anonymous users to modify
  existing files (e.g., to resume uploads) if filesystem
  permissions permit.

57d4ef078c Remove the outdated casts to "char *" from the setsockopt(2),
write(2), and getipnodebyaddr(3) calls.  Now all the above functions
accept "void *" in that arguments and have prototypes.  Thus, the
casts are useless under the normal circumstances (and would be harmful
if the functions had no prototypes.)

737d08f31e Use fgetln(3) to read lines from configuration files (ftpusers, ftphosts.)
Thus lines of any length can be handled, unlike before.

Don't assume that each line read from the files ends with a newline.

As a side effect in inithosts(), don't use automatic buffer at all,
utilize malloc(3) when getting local host name instead.

4b82fc955f Remove the setjmp/longjmp stuff completely. Use signal
handlers to set flags only (with exception for sigquit(),
which still seems to call some non-reentrant functions on
its way to _exit(2).)  That must eliminate the possibility
of catching SIGSEGV from following non-reentrant paths from
signal handlers.
